Common fib selling levels are the 1.618, 2.618, 3.618, 4.23. $4300 USD was smack in the middle of the 1.618 2.618 fib levels.

I think selling a little at different intervals and waiting for a larger pullback was reasonable -- we are definitely going to see a sub $3500 price *sometime*, just hard to say when. I actually sold some myself and think it was a mistake, better to have evidence of a top than try to prematurely predict it.
